Checking for care: what is unusual about this picture of the lunar Crescent?

We all know that the day sky different from the night. A truly mesmerizing night and day — at best — blind. And boring it is. Night, stars, satellites, milky Way, planets, Moon. And the day only the Moon. But wait… Astronomer Stephen Bellavia from the Brookhaven national laboratory made a great picture of the lunar Crescent on Monday and handed over to Gizmodo, the website that published it. Look at it closely. Do you notice anything unusual?

But this is a tiny Venus!

Let’s take a closer:

Venus in the daytime sky

Venus, being a sphere, like our Earth and Moon, has its phases. Because to the naked eye it commonly seems to be the brightest star in the sky, its phase is difficult to distinguish without a telescope. Bellavia was able to capture both of the Crescent in a single shot. He use camera body Canon EOS Rebel SL1 with Sigma 70-300 mm lens (and a tripod, presumably).

Who would have thought that such cool pictures of the sky can be done with such equipment available.
